NVIDIA GeForce GTX 680 Review: Retaking The Performance Crown
by Ryan Smith on March 22, 2012 9:00 AM ESTPortal 2
Portal 2 continues the long and proud tradition of Valve’s in-house Source engine. While Source continues to be a DX9 engine, Valve has continued to upgrade it over the years to improve its quality, and combined with their choice of style you’d have a hard time telling it’s over 7 years old at this point. Consequently Portal 2’s performance does get rather high on high-end cards, but we have ways of fixing that…
Portal 2 ends up being the strongest lead yet for the GTX 680, with the GTX 680 taking a 17% lead at 2560. What’s especially interesting though is performance in the bonus round with SSAA enabled – the GTX 680 takes a wholly unexpected and completely stunning 44% lead over the 7970. In fact it beats out everything here, including the GTX 590 and Radeon HD 6990. Meanwhile the lead over the GTX 580 is even more amazing, with the GTX 680 leading by 67% at these settings.
As it stands the GTX 680 is the first single-GPU card to do better than 60fps, and it does so in a landslide. All things considered, for a lack of memory bandwidth and ROP changes compared to Fermi GTX 680 does extremely well here.

Wait the boost speed is 1110 vs 1005 right? So 10% faster in shader performance, which will = about 5% in benchmarking performance in the best case.Nothing to see here move along.

Well, 7970@1.1GHz beats plain 680.SlyNine - Thursday, March 22, 2012 - link
Who cares, I wan't to know what the card comes shipped as. Thats what matters, anything extra you get out of that is exactly that, extra. What comes out of the box, thats what they are promising.BoFox - Friday, March 23, 2012 - link
Wait, you mean that HD 7970 needs to be overclocked by more than 20% in order to beat plain 680?How about overclocking that 680 by 15% like most review sites show is possible?
Then the 7970 would need to be overclocked by an impossible 35% in order to beat a 680 overclocked by 15%.
That was a nice try, Janooo!

It seems you missed the point.Whatever speed 680 has 7970 can match it. These cards are equal in this regard.
When they have the same clock speed then it looks like 7970 is faster.
Look for AMD to release a faster card soon.

We will have to subtract some mhz from the 7970 for having a larger core with more die space to make it fair, so transistor for transistor Kepler wins big.CeriseCogburn - Friday, March 23, 2012 - link
Plus were going to have to subtract more from The Heatie because it cheats on ram size too.Thanks Janooo you have great ideas.

Ok, if I go by your analogy and say that overclocking GTX 580 to the same speed as HD 6970 (880 MHz) makes both cards "equal in this regard."When they have the same clock speed then it looks like GTX 580 is faster.
Look for Nvidia to release a faster card soon ultilizing that 8-pin PCI-E connector on the PCB (which it did not need in order to beat HD 7970 overclocked or not).

680 has made 1,900mhz and makes well over 1,280 ouit of box reference...SlyNine - Thursday, March 22, 2012 - link
Why, thats how it is setup stock. That is how EVERY SINGLE CARD will come.
